HORSE'HAY-RAKE.

SPECIFICATION forming part of Letters Patent No. 266,288, dated October 24, 1882.

Application filed September 4, 1882. (N0 model.)

To all whom it may concern:

Be it known that I, WILLIAM H. HALL, of Tittin, in the county of Seneca and State of Ohio, have invented certain new and useful Improvements in Horse Hay-Rakes, of which the following is a specification.

Various constructions have been adopted in order to so connect the power derived from the draft of the team with the rake-head as to roll or oscillate the latter upon its hearings to dump the accumulated load. In the present case I propose to employ an oscillating rake-head, which may at the same time be a through-axle, and to connect loose spur-pinions carried in bearings thereon and normally constantly driven by spur-gears on the hubs of the gearing-wheels, or in an axial extension therefrom, with a friction device in such manner that they may at any time be prevented from rotation, and therefore carried on about the periphery of the spur-gearing in its continued revolution to cause the rake-head to rock upon its axis. I also propose to adopt certain novel constructions in carrying out this invention, such as will hereinafter appear, and to embrace within it certain modifications, also alluded to in proper order in the ensuing description.

In the drawings, Figure l is a perspective view of a horse hay-rake embodying myinvention in the simplest form now known to me; Fig. 2, a side elevation of said rake, partly in section; Fig. 3, a longitudinal elevation of the rake-head and its attachments; Fig. 4, a plan of the rake-head and its attachments; Fig. 5, a longitudinal section, in elevation, of a portion of the head enlarged; and Fig. 6, a transverse section through the head, near the'end of the same.

A is the oscillating rake-head; B, the carrying-wheels, and O the thill-frame hinged to the rake-head. So far as thehead,rake-teeth,and thill-frame are concerned, they may be of any ofthe usual and approved patterns. The head, as before stated, may be coincident with the through-axle, the wheels running directly upon its ends, as in a wagon. I have, however, shown it as provided with short metallic stubaxles (t to receive the wheels, which axles are secured substantially in the manner described in an application heretofore filed by me for Letters Patent of the United States. An or dinary link and foot-lever arrangement, D, or its equivalent, is provided to hold the head to its work or to return it thereto, if at any time necessary.

Upon the hubs ot' the carrying-wheels are mounted spur-gears b, bolted to or cast as a part of such hubs, or, if desired, connected therewith by backing-ratchets for the usual purpose. With these gears engage loose spurpinions I), carried by the rake-head, and under ordinary circumstances turning idly with the revolution of the gears. If, however, these pinions are locked against revolution, they will be carried forward by the gears in an are concentric with the axis of said gears, which axis also corresponds with the axis of oscillation of the rake-head, carrying the latter along with them, and raising the teeth sufficiently to drop the accumulated load. Now in order to cause this look I adopt the following arrangement: The pinions are supported on short shafts or spindles b running either loosely on these shafts, or the shafts themselves fixed to the pinions and turning loosely in their bearings. It will be sufficient to describe the first form. A casting or box-bearing, E, is secured to the top of the rake-head at each end, having at its outer extremity a broad disk or flange, e, which faces a corresponding disk, b upon the inner side of the adjacent pinion. The spindle which bears the pinion is formed with a head or cap, so that if moved longitudinally toward the center of the rake-head it will tend to draw the pinion and its disk against the disk upon the casting. A squared shank runs from the spindle through a corresponding sleeve in the oastinglongitudinally of the rake-head, and beyond this sleeve makes for the purpose of nice adjustment to its worka screw-joint, with the rod F connected to a lever, G, near the center of the rake-head. There being two rods-- one from each end of the rake-head-the same lever will serve for each, their pivotal connection therewith being outside their pivotal point and on opposite sides thereof, as will be understood. A spring, g, attached to .the rake-head, presses against a log or spur from the heel end of the lever, so as to hold it normally down,leaving the spur-pinions away from the friction-disk and free to turn.

A sliding rod, H, is passed through a bore in the rake head, and connected with the forcearm of the lever G by a slot and pin or otherwise, so as to compensate for their divergence of motion when operated. To the free end of this rod, beneath the rake-head, is attached one arm of a foot-lever, I, fulcrumed in a pendulum, 1', from the thill frame, and upon its other or forward arm provided with a pedal conveniently reached by the driver in his seat. \Vhen this foot-lever is depressed the rod will be raised, carrying with it the free end of the double lever on the rake-head and drawing in the tension-rods forcibly, so as to clamp the pinion-disks against the disk on the rake-head, thereby locking the pinions, preventing their rotation, and causing them to be carried forward by the gear-wheels to lift the rake-head. As soon as the load has been dumped, and as soon as the pressure has been released from the foot-lever, the spring upon the rakehead will restore the double lever and the tensionrods to their normal position, again permitting the pinions to run free. In these movementsthe rise and the fall of the rake-headthe pendular fulcrum of the foot-lever will permit it to play longitudinally to account for the hing ing of the rake-head upon the thill-frame, as explained in another application prepared by me and about to be filed, in which this is made a special feature.

In order to prevent hay or other substances from getting in between the intermeshing gears and pinions, and thus clogging or breaking them, a shield, K, of the form shown may be employed to cover and protect the sets at each end. For this purpose the flanges of the box-bearings are provided with ears L, and the sleeve-casting K, forming the outer support of the stub-axle and abutmentfor the wheelhub, has also an ear, 7:, whereby said shield may be readily attached.

The disks or flanges upon the pinions and the counter disks or flanges upon the boxes may be smooth-faced or corrugated, whichever is preferred. Ifsmooth, they should be ground to a suflicient frictional fit. The box-flanges may be chambered and a button or seat of wood or other suitable material inserted, against which the flanges of the pinion will be clamped; or the flanges on the boxes may be removed and the periphery of the pinion-flange widened, so that a small friction-block held over it by a short bell-crank that is pivoted to the head and operated by suitable lever mechanism may be brought to bear to stop both it and the pinion from revolution. As heretofore suggested, also a rotating through-axle or half-axle may be employed with a single spur-gear keyed thereto at or near the center of the rake, and a spurpinion carried upon a yoke from the integral or divided rake-head oscillating about this axle placed in mesh with said gear, and locked or released by a friction-clutch, as above, to dump or drop the rake. Hence I do not confine myself to the specific location of the gears and pinions shown, nor to the specific form of the friction-clutch, nor yet to the precise mechanism referred to as employed for operating the latter; but

I claim as my invention- 1.

5. The combination, substantially as hereinbefore set forth, of the oscillating rake-head, draft or carrying wheels by which it is supported, spur-gears upon the hubs of said wheels, flanged spur-pinions engaging with said gears, stubs or spindles upon which these pinions turn loosely, boxes upon the ends of the rakehead through which the squared shanks ofthe spindles are carried, flanges upon said boxes opposing the flanges upon the pinions, and rods connecting said shanks to a double or compound lever at or near the center of the rake-head, whereby the pinions may be simul-' taneously moved in against the box-flanges to prevent their rotation by frictional contact therewith.
